ECISS/TC 109 - Coated and uncoated flat products to be used for cold forming

This document applies to cold rolled non-coated low carbon steel flat products in rolled widths equal to or over 600 mm and in thicknesses equal to or less than 3 mm, delivered in sheet, wide strip, slit wide strip or cut lengths obtained from slit wide strip or sheet.
It does not apply to cold rolled narrow strip (rolling width < 600 mm) or to cold rolled flat products for which there is a specific standard, in particular the following:
-   cold-rolled low carbon steel flat products for cold forming (EN 10130);
-   cold-rolled non-oriented electrical steel sheet and strip delivered in fully processed state (EN 10106);
-   cold rolled electrical non-alloy and alloy steel sheet and strip delivered in the semi-processed state (EN 10341);
-   cold reduced blackplate (EN 10205);
-   steel sheet and strip for welded gas cylinders (EN 10120);
-   cold-rolled uncoated non-alloy mild steel narrow strip for cold forming (EN 10139);
-   cold-rolled structural steels for general purposes;
-   cold-rolled flat products made of high yield strength for cold forming (EN 10268).

This document specifies the requirements for laser welded tailored blanks (LWB) made of steels for all cold or hot forming processes.
This document is applicable to all steel grades with or without metallic and/or organic coatings, having uniform or different sheet thickness, welded with or without extra material addition.
After the welding process, LWB are further processed to pressed parts by forming operations under the responsibility of the processor.

This document specifies requirements for continuously organic coated (coil coated) steel flat products. It particularly specifies the performance requirements.
The products covered are wide strip, sheet cut from wide strip, slit wide strip, strip rolled in widths less than 600 mm and cut lengths (from sheet or strip).
NOTE   National provisions can set up relationships between the performances of the coatings as required in this document and the outdoor atmospheres and ambiances required for a relevant building under study.
This document is not applicable to continuously organic coated flat products made of:
- tin mill products;
- electrical steels.

This document specifies requirements for tinmill products in the form of sheets or coils. Tinmill products consist of single and double reduced low carbon mild steel electrolytically coated with either tin (tinplate) or chromium/chromium oxide (ECCS) or (ECCS-RC) (see 3.3).
Single reduced tinmill products are specified in nominal thicknesses that are multiples of 0,005 mm from 0,16 mm up to and including 0,49 mm. Double reduced tinmill products are specified in nominal thicknesses that are multiples of 0,005 mm from 0,12 mm up to and including 0,29 mm.
NOTE 1   Other thicknesses can be ordered upon agreement.
This document applies to coils and sheets cut from coils in nominal minimum widths of 600 mm.
NOTE 2   Standard width coils for specific uses, e.g. tabstock, can be slit into narrow strip for supply in coil form.

This document specifies a method using a barcoding system for tracing isolated defects that can be present in the following kinds of coated or uncoated steel flat products, for example:
-   electro-galvanised surface;
-   galvanised surface;
-   galvannealed surface;
-   cold rolled surface.
This method, named "quality tracking", aims to transfer additional material information to steel users, in particular the location of some isolated defects, in a reliable way. This method enables the manufacturer or purchaser to remove blanks or coils containing defects.
The method uses a 1D barcode to identify each section of steel strip.
NOTE 1   The stakeholders most involved in this technique are suppliers of steel flat products, car makers, appliance makers, part manufacturers, blanking line builders, steel processors, service centres, etc. All stakeholders can benefit from this project since defects can be traced, and, therefore, the steel containing defects can be eliminated or set apart of the production line.
NOTE 2   In the first stages of development, this method was called "defect tracking" (see [3]) and has been changed into "quality tracking" at the beginning of the standardization process.    
NOTE 3   Quality tracking can be applied to other types of coated or uncoated steel flat products such as pickled and oiled, organic coated, and steels for packaging. Quality tracking can be applied for coiled materials for which the technology of quality tracking is applicable.
NOTE 4   If quality tracking data are used outside of the purpose of quality tracking, it is under the responsibility of the user.
NOTE 5   Quality tracking can be applied to other materials than steel.
NOTE 6   The way to collect the information to be transferred to the user is out of the scope of this document.
